More of a vBulletin man myself, but I get what you mean. There were so many small, autonomous little niche communities and people took their time to learn how each one worked. Forums had their problems but I do think the time before upvotes/down votes was a very different dynamic, where not every judgment felt like it was being transmitted.

Ah, vBulletin. I confess I don't recall if there was any important difference to me. And looking on https://forums.sufficientvelocity.com, which I like, it seems to run a thing called XenForo? Anyway, the look-and-feel of all three are similar.

But that sounds kinda unstable and doesn't really provide the full benefits we expect from a...

Oh.


Most of the work is probably boring and not consequential on its own. But I think that's sepaerate from whether it's reasonable to encourage people to draw an ethical line. We probably wouldn't feel comfortable with someone who knowingly did work for the KKK, even if that work was just making photocopies, picking up office supplies, and keeping track of membership dues.

I always wondered why we don't see more Sterling Engine based heat pumps. IIUC they can use almost any gas including air.

Because they're sensible heat machines, instead of latent heat machines. In a perfect frictionless vacuum, both of these can achieve the same theoretical efficiency. In practice, not so much. In particular, the isothermal heat exchange of the ideal Stirling cycle requires heat exchangers with no thermal resistance (and therefore no temperature difference). A latent heat pump has a much easier time to very closely approximate isothermal heat exchange because condensation/evaporation temperatures at a given pressure are essentially constant.

What is the back of the envelope efficiency penalty we're talking about here?


Thank you!

Note that OpenAI has jettisoned every other supposed value they had (releasing their work as open source, not working on military applications, being a nonprofit). I'm sure we can rely on them this time.

And Anthropic are the good guys? They are talking insane stuff these days. May be we can trust zuck after all

None of them are the good guys. For one they're all happy to participate in genocide in Gaza.

Comments like these I'm willing to bet are because of the Reddit sub that's bringing Redditors with drop-mic comments in here. A ton of these things, usually but not always down voted. I think when they start hitting the top it's time to find threads without any possibility of Israel, Trump or Epstein possibly being brought up. I almost miss the old new-JS-framework complaint posts.

I would take that bet, anyone can examine my comment history and see that I've been participating on this site for a decade. Regardless, this comment violates the site guidelines.

I can promise you ranty political one-liners about Israel (your mic drop Reddity comment) violates guidelines about bringing politics unnecessarily into the picture. I'm not insinuating you're astroturfing or shilling; I would say you're unfortunately real.

The guy developed his own DIY radiative cooling paint mixture and tests it thoroughly. He also tests a commercially available paint in a recent video.


If a DIY plotter would do, this site has a long list of different projects

What if I want a cabinet sized rotating head printer that can print carbonpaper triplets, sounds a machinegun, and has LP0 ON FIRE error message

> Phones are more robust these days than ever.

They are certainly not more robust than ever. The trend of screen glass extending all the way to the edge of the phone and around it has ensured that most people need a case. Back in the 2010s I never used one and my phone would survive many drops.


I think we are kidding ourselves if we think writing software was only accessible to the cognitive top 10%. And even if that were the case for the highly paid software jobs, there was a long tail of WordPress customization type jobs that required less experience and will probably be going away.

Sure but if the customer installs the app on their own computer how do companies charge them a recurring subscription fee? Adobe can get away with it but most cannot.
